CHOKER-HOOK.

Specification of Letters Patent.

Patented July 25, 1316.

Application filed August 3, 1914. Serial No. 854,745.

T 0 all whom it may concern:

Be it known that I, ARTHUR G. AsHBY, a citizen of the United States, residing at Carrollton, in the county of Cowlitz and State of Washington, have invented certain new and useful Improvements in Choker- Hooks, of which the following is a specification.

My invention relates to choker hooks.

The primary object of my invention resides in the provision of a novel chokerhook for engagement with a piece of cable, the latter being wrapped about logs when hauling them from the woods to the mill, the hook having novel locking means associated therewith for preventing the cable from becoming disengaged during the transmission of the logs, and thus prevents a great delay as in the ordinary devices of this character.

Another object of my invention resides in the provision of a novel fastening means associated with the locking means for absolutely preventing the cable from becoming disengaged and which fastening means is releasably associated with the locking means for facilitating the removal of the cable when desired.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, eflicient in operation and one that can be manufactured andplaced on the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings pointed out in the claims forming a part of this specification.

In the drawings :Figure 1 is a side elevational view of my invention in locked position; Fig. 2 is a top plan view of the same; and Fig. 3 is a perspective view of the hook proper. I I

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts throughout the different views, I provide a substantially flat rectangular shank 1, formed preferably of any desirable metal, having an opening 2- arranged therethrough for facilitating the attachment of the shank to a cable, the shank being further provided with a smaller circular opening 3 adjacent the opening 2, for a purpose to be hereinand.

after described. The opposite end of the the end of the shank as at 6, the slanting surface being provided intermediate its side edges with an upstanding ear 7, the lat ter havmg a transversely extending opening 8 therethrough through which is engaged a pivot pin 9 for pivotally mounting my lmproved locking element generally designated 10. 7

My improved locking element in this instance consists essentially of a keeper 10, the latter being substantially rectangular in plan and having the side edges thereof arranged in alinement with the side edges of the shank l and having one end thereof enlarged into a circular formation and bifurcated to provide a pair of spaced parallel rounded ears 11, the latter being disposed upon opposite sides of the ear 7 and connected thereto by the pin 9. In order to facilitate the moving of the rounded ears 11, I have slightly depressed the slanting surface 6 as clearly shown in the drawings. The intermediate portion of the keeper 10, which is slightly curved, is arranged in engagement with the upper outer surface of the hook 5 and extends at-an acute angle to the shank 1 to provide a substantially V-shaped opening 12. The flange 13 is formed by'bending the free terminal of the keeper and arranging the same in intimate contact with the shank as at 13 and which flange is further provided with an opening 1st arranged in alinement with the opening 3 in the shank, the freeterminal 13 being further provided with a longitudinal slot 15 which communicates with the opening 14:

for a purpose to be hereinafter described.

It will thus be apparent that the keeper which extends across the hook serves to clamp and look a cable in position, any.

the tapering head 18 of the pin, the latter being enlarged at a point in alinement with the upper surface of the shank to provide a shoulder 19, the latter being arranged in close relation with-the upper surface of the shank and preventing accidental displacement of the pin from the shank. The upper enlarged end of the pin is provided with a fiat upstanding head 20, the latter being provided with a laterally extending lugf2l which passes through the slot 15 when the locking element is being secured in place.

Upon slight rotation of the pin so that the lug 21 is placed out ofalinement with the slot 15 accidental displacement of the locking element is prevented.

The operation of my invention is as follows :When it is desired to carry a number of logs from thecwoods to the mill, a.

cable, not shown, is passed about the logs and engaged bythe hook 4:, and the locking element 10 is moved about its pivot and secured in place by the pin 20, the latter, because of the lug 21 when rotated out of alinement with the slot 15, preventing the accidental displacement of the locking element from the shank of the hook.

Although I have shown and described the preferred embodiment of my invention, I desire to be understood thatI am not limited to the exact details shown; however, I

desire that great stress be laid upon the arrangement of the locking element associated with the hook and the novel fastening means for removablyholding the same in engagement with the shank of thehook.

shank receives and supports a logging cable thereby relieving the weightand strain from the pivot point andgreatly lengthening the longevity, of the device and in addition serves the purpose of contactingv with the inner surface of the locking element to prevent the latter from directly engaging the shank, thus reducing a possibility of breakage of the element to a minimum.

From the above description taken in connection with the accompanying drawings it can easily be seen that I have provided a device that is simple in construction containing but a few simple parts that can be .cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A choker hook including a relatively fiat shank having an opening in one end Copies of this patent may be obtainedfor It is to V be. noted that the hook 4 carried by the I thereof for adjustment'with a cable, a flat pointed hookformed on the opposite end of the shank for supporting a logging cable, an arcuatelocking element pivotally mounted on the outer face of the hook and arranged to contact intimately with the free end'of the hook and theshank and cooperating with the shank and hook for efficiently clamping a cable thereon, and fastening means associated with the free end of the locking element for removably holding the locking element in engagement with the the opening provided by the element to the shank, and fastening means associated with the shank for removably holding the flange in engagement with the shank. v

3. Al choker hook including a shank having an opening in one end thereof for attachment with a cable, the opposite end of the shank being enlarged, an arcuate hook having a flat point formed on the enlarged end of the shank for supporting a cable, the

outer face of the hook slanting diagonally, an upstanding ear formed on the outer face of the hook, an arcuate locking element pivotally mounted about theyear and arranged in intimate contact with the under surface of the hook for reduclng the possibility of breakage of the element to a minimum, a

flange extending from the free end of the element and adapted for intimate contact with the shank and being so arranged to provide a V-shaped opening for causing the element to efiiciently clamp the hook of a cable in the V shap'ed end of the opening,

and a locking pin rotatably mounted in said shank for removably engaglng and holding the flange in intimate contact with the shank. ,7 V

In testlmony whereof I affix mysignature 1n presence of two witnesses.
